[TPR-SoB] Home Thread VI

Sorry all - Had to drop all my boxes at once. We had a power outage that killed one of the ACs in our server room and I couldn't take the extra heat. This isn't a datacenter so we don't have all the redundancy - waiting currently for a new AC motor to get it all running again. The "Burn-in" boxes were #1 to go down as they aren't used for production right now - just some vmware test machines.

Looks like my loss put us #6 in the dailies. Sorry!

I should be able to get most, if not all, of it back up and crunching sometime next week.

Also, Ive been with SOB for a long time - is there a better project for my ~48 xeon cores to be working on? I should have full availability of all of them until August, then the servers will be utilized more and more for production (work) related stuffs.

Prime 95 v26.3 has been released, and we need a few testers for SoB.Timings, before and after would be very helpful.It should be possible to simply: 1) stop your client2) Back up your folder, just in case3) replace your old executable with the new executable (executable only, not your prime.txt)4) start your client5) make sure you resumed where you left off and are still connected to the SB server and not to mersenne.org instead. I also need a MAC user to test a new package. Please PM me.The http://www.seventeenorbust.com/download/ download page has new packages that need to be checked out if anyone has the time. Make sure the links work, etc.You can use them as a source of the new v26.3 executable if you want. Please be sure to check your prime.txt file for the correct username. You may, and probably should, use your current prime.txt file unless it does not have your correct user name in it.

I'm behind a proxy, and although I've googled, I can't find an exact format to use in the prime.txt file for this. Would it just be hostname:port? Then to launch the program from a terminal I'd just do "open Prime95.app"? I'm a nub, sorry

There was an algorithm that took the current N value and the remaining K's relative primality, to calculate a new-prime-found probability. Not sure if it was ever accurate, but having any info on what it would say about current levels and any analysis on how accurate it's been would be interesting.

Any idea what kind of firepower could bring TPR-SoB back to #1?

Shout out to Beeba, notagain, Hades, edgan, BartMan, Manwe, Mattbots, robaustin, pudknocker, azdawg, floh - thanks for keeping the flame burning - and also to all the old SoB lurkers!

The current runtime on an i5-3570 @stock 3.4Ghz is about 4-4.5 days but since there are 4 cores, it does on average one test per day.

As for getting to #1 keeping our position would take ~7 i5-3570 based on my roughly 7T/day production and losing 48T to Russia. I'm not sure how that translates to other architectures/cores. We will catch Anandtech before they catch us by about a year. The other team with an overtake date is a long way off since we have a big lead and they aren't beating our production by much.

Looks like we are only losing 22.2T to Russia now, also we have picked up the pace enough that Russia is the only team with an overtake date. Somehow, I grabbed 1st in the Dailies according to SoB's stats yesterday; though I don't know how much longer I'll be able to keep up this production.

Looks like I have a machine or two that decided not to contribute, I'll have to see if I can find it when I have time. Stricker your daily average is impressive, most impressive. It would be nice to get one more contributor like you to hold off Russia.

@BartManInNZ, looks like that will be a while. You will probably have to pass beeba to get in the top 10 for TPR since I will be overtaking you either later today or early tomorrow. At least you are currently in the top 100 for the project.

Hey all! I'm feeling a bit nostalgic today (after reading about the GIMPS find on the main page) and decided I should "break in" my new server. I'm waiting on RAM ATM, but it should be here by the end of the week. In the mean time I plan to add pretty much every computer in my house for a while. It will be interesting to see how much I can produce. It has been years since I last participated in the project, but I'm excited to get back into it.

Welcome back! From experience the latest client is as easy as you describe and is very good at optimising itself for whatever CPU you throw at it. I stick with the Free-DC stats - cleaner and detailed for my needs. Hoping to get my own CPU's back up and crunching shortly after an enforced hiatus.

Now is a great time to make a move.With a couple of additional people contributing, second place (team) overall would drop fairly quickly.Also, figuring the last prime, found late in 2007 had N=13M, and that first time PRPs are closing in on N=24M, SoB is certainly due for a prime.

Not sure... I'm only running 7 workers at present. The PC clients are causing enough damage to the WAF rating of the network right now, so I want to make sure the server has a core dedicated to prevent stuttering/lag. I'm not really sure how to guage the output increase on this new client either. Any tips for guaging performance would be appreciated.
